Hydrogen is gas that already exists in the atmosphere together with nitrogen and oxygen. Since hydrogen is very light gas, it does not stay in one location after being emitted during the use of fuel cells but spreads and disappears into the air quickly.The safety accident rate of hydrogen is extremely lower than that of batteries, and most hydrogen-related accidents were caused due to human error such as carelessness when handling hydrogen tanks and the failure to inspect the facility.

The hydrogen tanks of Doosan Mobility Innovation are the first hydrogen tanks for mobile fuel cell powerpack to have received Korea's KGS certification, and it is currently in the process to obtain international certifications such as ISO and DOT. It passed numerous drop tests and shot tests, and showed strong durability with no ripping or ruptures despite dropping from 150m high.

The hydrogen tanks of Doosan Mobility Innovation are Type IV composite material tanks with a high storage efficiency. The hydrogen tank is a proven technology that is used to make fuel cell vehicles and is becoming more common in markets because of its numerous strengths.As it is ultralight, it increases fuel efficiency and payload, and more energy can be stored per volume as it has a higher storage density. And the carbon fiber composite material minimizes external shocks by withstanding all structural forces applied to the tank.

A fuel cell drone shows the exact remaining flight time on the controller monitor of the PC/mobile user. Therefore, the user can operate the drone until they completely use up the hydrogen. This is one of the biggest strengths of a fuel cell drone compared to a battery drone, whose remaining flight time cannot be predicted accurately using the remaining battery level.

There is no need to worry about the hydrogen tank falling because it cannot be released when the drone is in flight mode. Even if an error occurs and hydrogen supply stops during flight, the drone will initiate an emergency landing using the hybrid battery.

When a customer orders hydrogen through online/mobile e-commerce, a fully-fueled hydrogen tank is delivered to the address of the customer and the empty tank collected within 1 to 7 days of the day of the order. The hydrogen tanks are the assets of Doosan Mobility Innovation, and the customer only orders the hydrogen gas. Besides this, Doosan Mobility Innovation strives to provide a convenient and quick hydrogen supply solution by offering various hydrogen supply options.

Doosan Mobility Innovation is the only fuel cell company that has a hydrogen supply chain. We have completed our construction of a hydrogen supply chain in South Korea, held meetings to discuss specific cooperation methods with numerous large companies in the US, and completed discussions on the construction of a hydrogen network in China.

There is no need for a customer to refuel hydrogen directly to the tank inside the fuel cell because a fueled hydrogen tank will be delivered to the them ahead of time.The used-up hydrogen tank can be separated in one touch via the fuel cell system. The customer can use the fuel cell again immediately after inserting the new filled hydrogen tank.

While liquid hydrogen is denser than the high-pressure hydrogen we use and, therefore, more hydrogen can be stored per volume, it will still take some time for it to be commercialized since the equipment needed to refuel liquid hydrogen and to vaporize liquid hydrogen into hydrogen gas is heavy. Our company’s powerpacks can also be used with liquid hydrogen once the related infrastructure is built.
